Ghella [55]

Answer:

The value 10 years is the population mean

Step-by-step explanation:

A sample consists of some observations drawn from the population, so a part or a subset of the population which in this case is the number of horses with colic.

A sample mean is the mean of the statistical samples while a population mean is the mean of the total population.

Thus, in this case, the sample mean is the mean age of the horses with colic while the population mean age is the mean age of all the horses found at the clinic.

Therefore, the mean age of 10 of the horses seen at the clinic would be the population mean.

HELP! Find the value of the 30th percentile of the following set of data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152

Let list the data in ascending order 100, 100, 105, 113, 129, 132, 146, 152, 176, 200

There are ten numbers so the thirtieth percentile would be the .3 * 10

= 3rd number, ordered from smallest to largest.

so the third number, the thirtieth percentile, is 105
